Arbor day~? Scold~! Guanyin, do you say that this kid has nothing to do all day long? Want to plant a tree? ”

Two days later, in the evening, in the Ganlu Palace, when Li Er was reviewing the recital, he couldn't help but smile at the eldest grandson Empress who accompanied him to review the recital.

At this time, Li Zexuan spent a whole day sorting out a proposal for Li Er to implement Arbor Day and advocate that the people in the states and counties of the Yellow River Basin build shelterbelts, during which he also went to the library of Yanhuang Academy to consult a lot of ancient books.

Oh, it is worth mentioning that the library of Yanhuang Academy, since the day it was built, Li Gang has been committed to expanding books inside, many princes and nobles can't get the only books, the old gentleman can get them, and after handing them over to the printing department of the workshop, they will be sent to the Red House of the Academy to expand the library! Today, the library of Yanhuang Academy can be regarded as the second largest collection of books near Chang'an City!

As for the first, it must be royal! However, if this momentum continues, the library of Yanhuang Academy will have more books than the royal family, and it will be a matter of time!

But even though Li Zexuan spent a lot of effort for this piece of music, Li Er's first reaction when he saw this piece of music was still sneering, no wonder Lao Li, but in all dynasties, emperors have always only cared about people's livelihood and their own country, who would be idle and concerned about environmental protection and tree planting?

In the whole of ancient China, no one would have this concept!

"Planting trees~? Your Majesty, whose twist is this? Isn't it Yong'an Hou who presented it~? ”

Hearing this, Empress Eldest Sun asked with a smile on her face.

With a blue heart, she can hardly guess who the owner of this strange letter is without Li Er's reminder? At present, there are ministers in the court who are so out-of-the-box, except for Li Zexuan, I am afraid that there will be no one else!

"Hmmm! Guanyin is really smart, but it was written by Li Zexuan! Hey~? This kid seems to be writing a little interesting! ”

Li Er laughed while watching, but suddenly he couldn't laugh anymore, and his face showed surprise.

Empress Eldest Sun was surprised in her heart, she turned sideways quietly, and set her eyes on Li Er's recital, gradually, there was no longer a disdainful laughter in the hall, but a solemn atmosphere gradually permeated the hall, half an hour later, Li Er stood up, took two steps with his hands in his hands, and then instructed Zhao Song in the hall:

"Tomorrow morning, Fang Xuanling, Du Ruhui, eldest grandson Wuji, Xiao Yu, and Yan Lide will be left to discuss matters, and Li Zexuan will enter the palace tomorrow to wait for driving~!"

Zhao Song's eyebrows twitched, and he hurriedly stepped forward and solemnly arched his hand: "The old slave obeys the order~!" ”

……………………………

"Xianggong, do you think Your Majesty can listen to what you say~?"

Yunshan Courtyard, after dinner, Han Yuxi came to the study with a cup of hot water, and saw that Li Zexuan was reading, she couldn't help but ask out loud.

Obviously, she had also read the contents of that excerpt!

Li Zexuan raised his head and said with a smile: "Hehe! Wife! There is a saying called doing one's best, knowing the destiny of heaven! This excerpt is already the best level that you and I can play, and I also asked Mr. Li Gang and Ma Zhou to help check it. If the saint can listen to these words, it will naturally benefit future generations, if you can't listen to it, I will also find a way to do my part, after all, I don't want our future children and grandchildren to not even have a sip of clean water to drink~! ”

This is not alarmist, according to the current development trend of the Tang Dynasty, it will enter a comprehensive prosperity in less than 20 years, and the population in Chang'an will continue to increase dramatically, which will bring great pressure to the ecological environment of the Loess Plateau, and the water of the Yellow River will become more turbid, and the eight rivers will surround Chang'an, but at that time, can the current eight water veins really support the super Chang'an City at that time?

In fact, the Yellow River was not called the "Yellow" River at the beginning in ancient times, but called the "River", and the "River" was called the "Yellow River", which was because the color of the river changed, so the Yellow River was surnamed "Yellow".

The name "Yellow River" began in the Eastern Han Dynasty, but as early as the Spring and Autumn Period, there were written records that the river was unclear. However, during the Han Dynasty, the yellow color of the river became more noticeable, so much so that people called it the "Yellow River".

In the middle of the Han Dynasty, the great Sima Shi Zhang Rong (character Zhonggong) said: "The river water is heavy and turbid, and it is called one stone of water and six buckets of mud", which is a phenomenon that no one has said in the early Han Dynasty.

In the middle of the Western Han Dynasty, Jingshui was famous for its turbidity currents. In the time of Emperor Wu of the Han Dynasty, "one stone of Jingshui, several buckets of mud", at that time to divert Jingshui to irrigate farmland, and also improve the role of soil. The Jingshui and Weishui basins are the earliest areas for agricultural development on the Loess Plateau, and with this development, the original vegetation has been destroyed, and the soil erosion has increased, resulting in the Yellow River becoming more and more turbid, and it has probably developed to become conspicuous in the Eastern Han Dynasty, thus giving it the name of "Yellow River".

As the Tang Dynasty enters a state of full prosperity, this Loess Plateau will feed more people, and a large amount of farmland will inevitably be mined at that time, and soil erosion in the Yellow River Basin will be more serious.

"Children and grandchildren..."

Han Yuxi's face suddenly became a little complicated, and she muttered in a low voice: "Xianggong, when will we have our own... Child? The concubine is sixteen years old this year! ”

With that, her face flushed with shame.

Li Zexuan almost vomited blood, this... The point of what he said is not here at all, right?

"Yah~! What are you going to do? Put down the concubine body! ”

"Hey, hey! Lady, don't you want to have children? Let's make a child! ”

.............

There is no need to mention it, early the next morning, the little couple was having breakfast in the courtyard, and Zhao Song came over to pass the decree and let Li Zexuan enter the palace and wait for the car.

Although Li Zexuan's face was silent, he still couldn't help but be happy in his heart, after all, he was not an orthodox civil official, and he was not as experienced as Wei Zheng and Fang Xuanling when he wrote excerpts, although the drafting process of this letter was helped by Li Gang, Ma Zhou and others, but he still had no bottom in his heart, and now that Li Er is willing to announce his entry into the palace, the matter has basically become a small half!

Several people rode fast horses and rushed all the way to the imperial city, handed over Dabai to Pang Feiji to take care of, Li Zexuan followed Zhao Song into the palace gate, and went straight to Taiji Palace.

In the Taiji Palace, Li Er and Baiguan are going to the early court, Li Zexuan is naturally impossible to go in at this time, and this thing is not the same as being late for class to make up a "report", the early dynasty is very formal.

Besides, Lao Li's holy decree was to let Li Zexuan wait in the Ganlu Palace, but he was not allowed to participate in the early dynasty.
